Question

在我的下面测试中，我尝试模拟超时，然后发送正常请求。但是，我得到了spray.can.Http $ ConnectionException：过早连接关闭（服务器似乎不支持请求流水线）

class SprayCanTest extends ModuleTestKit("/SprayCanTest.conf") with FlatSpecLike with Matchers {

  import system.dispatcher

  var app = Actor.noSender

  protected override def beforeAll(): Unit = {
    super.beforeAll()
    app = system.actorOf(Props(new MockServer))
  }

  override protected def afterAll(): Unit = {
    system.stop(app)
    super.afterAll()
  }


  "response time out" should "work" in {
    val setup = Http.HostConnectorSetup("localhost", 9101, false)

    connect(setup).onComplete {
      case Success(conn) => {
        conn ! HttpRequest(HttpMethods.GET, "/timeout")
      }
    }

    expectMsgPF() {
      case Status.Failure(t) =>
        t shouldBe a[RequestTimeoutException]
    }


  }

  "normal http response" should "work" in {

    //Thread.sleep(5000)
    val setup = Http.HostConnectorSetup("localhost", 9101, false)

    connect(setup).onComplete {
      case Success(conn) => {
        conn ! HttpRequest(HttpMethods.GET, "/hello")
      }
    }

    expectMsgPF() {
      case HttpResponse(status, entity, _, _) =>
        status should be(StatusCodes.OK)
        entity should be(HttpEntity("Helloworld"))
    }
  }

  def connect(setup: HostConnectorSetup)(implicit system: ActorSystem) = {
    // for the actor 'asks'
    import system.dispatcher
    implicit val timeout: Timeout = Timeout(1 second)
    (IO(Http) ? setup) map {
      case Http.HostConnectorInfo(connector, _) => connector
    }
  }

  class MockServer extends Actor {
    //implicit val timeout: Timeout = 1.second
    implicit val system = context.system

    // Register connection service
    IO(Http) ! Http.Bind(self, interface = "localhost", port = 9101)

    def receive: Actor.Receive = {
      case _: Http.Connected => sender ! Http.Register(self)

      case HttpRequest(GET, Uri.Path("/timeout"), _, _, _) => {
        Thread.sleep(3000)
        sender ! HttpResponse(entity = HttpEntity("ok"))
      }

      case HttpRequest(GET, Uri.Path("/hello"), _, _, _) => {
        sender ! HttpResponse(entity = HttpEntity("Helloworld"))
      }
    }
  }


}

和我的测试配置：

spray {
  can {
    client {
      response-chunk-aggregation-limit = 0
      connecting-timeout = 1s
      request-timeout = 1s
    }
    host-connector {
      max-retries = 0
    }
  }
}

我发现在这两种情况下，＆＃34; conn＆＃34;对象是一样的。所以我想当RequestTimeoutException发生时，将conn放回池中（默认为4？），下一个案例将使用相同的conn但此时此conn保持活动状态，因此服务器会将其视为分块请求

如果我在第二种情况下睡一觉，它就会过去。所以我想我必须在得到RequestTimeoutException时关闭conn并确保第二种情况使用一个全新的连接，对吧？

我该怎么办？任何配置？

你不应该阻止一个Actor（你的MockServer）。当它被阻止时，它无法响应任何消息。您可以将Thread.sleep和响应包装在Future中。甚至更好：使用Akka Scheduler。确保将发送方分配给val，因为它可能会在您异步响应请求时发生更改。这应该可以解决问题：

val savedSender = sender()
context.system.scheduler.scheduleOnce(3 seconds){
  savedSender ! HttpResponse(entity = HttpEntity("ok"))
}
